Huge bags of Tupperware from a shipwreck wash up on the beach in St Gweep and the locals are whipped into a scavenging frenzy, meanwhile Harry decides to lead a campaign against people who buy up property in the town for use as holiday homes.
Following an outbreak of vandalism by local kids Mary recommends punitive action but Angela suggests positive activities, in the process discovering bungee jumping, which she is keen to try, especially as the instructor is young and handsome. Other villagers also sign up but Angela begins to have second thoughts and only agrees to go through with it if white witch Holly gives her a lucky charm - a very large stone which makes her jump rather more spectacular than the others'. Meanwhile Mary forces the kids to paint a mural - securing herself an arts council grant along the way.
